DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to FIG. 1, a vehicle 10 is illustrated in accordance with a first embodiment.

The vehicle 10 includes a vehicle body structure 12 and a vehicle front end assembly 14. The vehicle body structure 14 includes a frame structure 16 shown in FIG. 2 separated from the remainder of the vehicle body structure 12. The frame structure 16 includes a floor panel 18 that at least partially defines a passenger compartment and frame elements forward of the passenger compartment and further includes a first front side member 20, a second front side member 22, a first hood ledge 24, a second hood ledge 26 and a dashwall 28. The first and second front side members 20 and 22 extend in a vehicle forward direction D_(F) from the dashwall 28 and the floor panel 18 extends in a rearward direction D_(R) from the dashwall 28. A brace 25 has a rearward end attached to the hood ledges 24 and 26 at a location above and spaced apart from the front side members 20 and 22.

An engine compartment is at least partially defined by between the first and second front side members 20 and 22, and between the first and second hood ledges 24 and 26 forward of the dashwall 28. The dashwall 26 separates the passenger compartment from and engine compartment.

The vehicle body structure 12 further includes an engine cradle 30 that is installed to the first and second front side members 20 and 22 and is located below the first and second front side members 20 and 22. An engine E is installed to the engine cradle 30 in a conventional manner.

The vehicle front end assembly 14, as defined herein, includes the first and second from side members 20 and 22, the first and second hood ledges 24 and 26, the engine cradle 30, a bumper assembly 32 (see FIGS. 3-5 and 9), push-off structures 34 (also referred to hereinbelow as outboard push-off structures 34 and shown in FIGS. 3-7, 9 and 15-18) and/or inboard push structures 36 (see FIGS. 9-15 and 18). The first and second hood ledges 24 and 26 and the engine cradle 30 are optional and not required in all configurations and embodiments of the vehicle front end assembly 14. It should be understood from the drawings and the description herein below that the vehicle front end assembly 14 can include: both the outboard push-off structures 34 and the inboard push structures 36; just the outboard push-off structures 34; or just the inboard push structures 36.

The outboard push-off structures 34 and the inboard push structures 36 are configured such that there is one outboard push-off structure 34 on the first front side member 20 and one outboard push-off structure 34 on the second front side member 22. Similarly, the inboard push structures 36 are configured such there is one inboard push structures 36 on the first front side member 20 and one inboard push structures 36 on the second front side member 22. Since the two outboard push-off structures 34 are identical (except for their being symmetrical mirror images of one another) and the two inboard push structures 36 are identical (except for their being symmetrical mirror images of one another), only the outboard push-off structure 34 and the inboard push structure; 36 installed to the first front side member 20 are described herein below and fully depicted in the drawings, for the sake of brevity.

As shown in FIGS. 2-3, 5 and 8-9, the first front side member 20 (hereinafter referred to as the front side member 20) has a front end surface 40, an upper surface 42, a lower surface 44, an inboard surface 46 and an outboard surface 48. The inboard surface 46 and the outboard surface 48 extend from the upper surface 42 to the lower surface 44 and from the front end surface 40 to the dashwall 28.

A rearward end of the first hood ledge 24 is attached to dashwall 28 at a location spaced apart from and vertically higher than the front side member 20. The first hood ledge 24 curves in an inboard and downward direction moving forward such that a front end of the first hood ledge 24 attaches to the outboard surface 48 of the front side member forward of the dashwall 28 and rearward of the front end surface 40 of the front side member 20. In other words, the hood ledge 24 extends upward, rearward and outboard from the front side member 20 proximate the front end surface 40 toward the upper portion of the dashwall 28.

The engine cradle 30 is attached to the front side member 20 and the front side member 22. The engine cradle 30 include four attachment structures that are fixed to the lower surface 44 of both of the front side members 20 and 22 in a conventional manner. Further, lateral side portions 30 a and 30 b of the engine cradle 30 are located beneath and spaced apart from respective lower surfaces 44 of the front side members 20 and 22.

The engine E is installed to the engine cradle 30 and extend upward therefrom between respective inboard surfaces 46 of the front side members 20 and 22. The engine E can be an internal combustion engine that includes a transmission, an electric motor, (with the vehicle 10 being an electric vehicle), or can be a hybrid power plant that includes both an electric motor and an internal combustion engine.

The bumper assembly 32 includes a pair of a bumper stays 50 (only one bumper stay is shown) and a front bracket 52. The bumper stays 50 are installed to respective opposite outboard ends of the front bracket of the bumper assembly 32, as shown in FIGS. 3-5 and 9. The bumper stays 50 are supported by the front side members 20 and 22, as described in greater detail below.

A description of one of the outboard push-off structures 34 (also referred to as the push-off structure 34) is now provided with specific reference to FIGS. 3-7, 9 and 15-18. The push-off structure 34 attached to the outboard surface 48 of the front side member 20 adjacent to the front end surface 40 of the front side member 20, as is described further detail below. An upper portion of the push-off structure 34 extends outboard from the outboard surface 48 and a lower portion of the push-off structure 34 extends downward below the lower surface 44 of the front side member 20 toward the lateral portion 30 a of the engine cradle 30 and the engine E.

The push-off structure 34 is formed from a plurality of plates and/or panels that are welded to one another. More specifically as shown in FIG. 7, the push-off structure 34 includes an outboard bracket 56, a lower main bracket 58, a lower reinforcement bracket 60, a first upper bracket 62, a second upper bracket 64, an inboard bracket 66 and a forward bracket 68.

The largest of the plurality of plates and/or panels of the push-off structure 34 is the outboard bracket 56. The outboard bracket 56 has an upper section 56 a, an outboard section 56 b and a lower section 56 c. The upper section 56 a, the outboard section 56 b and the lower section 56 c at least partially define a cavity therein. The upper section 56 a includes an upper flange 56 d that attaches to the outboard surface 48 of the front side member 20. The lower section 56 c includes a lower flange 56 e that can attach to the inboard push structure 36, when the inboard push structure 36 is employed, in a manner described in greater detail below.

When the push-off structure 34 is fully assembled, the lower main bracket 58, the lower reinforcement bracket 60, the first upper bracket 62 and the second upper bracket 64 are all nestled within the cavity C between the upper section 56 a and the lower section 56 c and between the outboard surface 48 of the front side member 20 and the outboard section 56 b of the outboard bracket 56, as shown in cross-section in FIGS. 15, 16 and 17. More specifically, the lower main bracket 58, the lower reinforcement bracket 60, the first upper bracket 62 and the second upper bracket 64 are all arranged within the cavity C and define a honey-comb-like or labyrinth-like assembly that reinforces the outboard bracket 56 against deformation in response to an off-center impact event.

The outboard section 56 b (also referred to as an outboard wall of the outboard bracket 56) has a rear end 56 f and a forward end 56 g. The rear end 56 f contacts a portion of the outboard surface 48 of the front side member 20 and the forward end 56 g is spaced apart from the front end surface 40 of the front side member 20. The outboard surface 40 of the front side member 20 is such that the outboard section 56 b (the outboard wall of the outboard bracket 56) and the outboard surface 48 of the front side member 20 define an acute angle α₁ therebetween that is greater than 25 degrees, as shown in FIG. 12.

The lower main bracket 58 and first upper bracket 62 are welded to one another and are arranged within the cavity C such that the first upper bracket 62 is located above the lower main bracket 58, as shown in FIGS. 15, 16 and 17. The lower main bracket 58 and the lower reinforcement bracket 60 are welded to one another and are positioned within the cavity C of the outboard bracket 56 such that the lower reinforcing bracket 60 is positioned inboard of a vertical part of the lower main bracket 58.

The lower reinforcement bracket 60 is located below and extends parallel with the second upper bracket 64. The first upper bracket 62 and the second upper bracket 64 are positioned within the cavity C of the outboard bracket 56 with the second upper bracket 64 being inboard of the first upper bracket 62. Contacting areas of the plurality of brackets are welded to one another where possible forming a solid structure that can resist deformation. Further, the lower reinforcement bracket 60 is welded to the lower main bracket 58, and, the lower main bracket 58 is welded to the first upper bracket 62, the second upper bracket 64 and the outboard bracket 56.

The inboard bracket 66 is attached to both the outboard surface 48 of the front side member 20 and the upper flange 56 d of the outboard bracket 56 of the push-off structure 34 via fasteners F₁, as shown in FIGS. 3 and 4. In other words, the inboard bracket 66 is sandwiched between the outboard surface 48 of the front side member 20 and the upper flange 56 d of the outboard bracket 56 of the push-off structure 34.

The forward bracket 68 is fixedly attached (via, for example, welding techniques) to the upper and lower sections 56 a and 56 c of the outboard bracket 56 covering an opening defined by the outboard bracket 56 exposing the cavity C. In other words, attachment of the forward bracket 68 at least partially covers and conceals the cavity C and forward edges of the lower main bracket 58, the lower reinforcement bracket 60, the first upper bracket 62 and the second upper bracket 64, as shown in FIGS. 3-6.

The push-off structure 34 further includes a joint bracket 70 that is attached to both a forward end of the hood ledge 24 and a mid-portion the outboard bracket 56 of the push-off structure 34. More specifically, the joint bracket 70 has a sloping portion 70 a and a vertically downwardly extending portion 70 b. The sloping portion 70 a is attached via fasteners F₁ to both a sloping portion of the hood ledge 24 and the upper section 56 a of the outboard bracket 56. The vertically downwardly extending portion 70 b of the joint bracket 70 is attached via fasteners F₁ to the outboard section 56 b, as shown in FIGS. 3 and 4.

The vehicle front end assembly 14 further includes a front bracket 72 that has a first portion 72 a and a second portion 72 b. The first portion 72 a is attached to the front end surface 40 of the front side member 20 along with the front bumper stay 50 of the bumper assembly 32 via fasteners F₁. The second portion 72 b is attached to a forward surface of the forward bracket 68 of the push-off structure 34 via fasteners F₁. The first portion 72 a of the front bracket 72 is basically a first planar portion and the second portion 72 b of the front bracket 72 is basically a second planar portion that is off-set from the first portion 72 a such that they are not co-planar. The first portion 72 a of the front bracket 72 covers at least most (part) or all of the front end surface 40 of the front side member 20 and the second portion 72 b of the front bracket 72 covers at least part or all of the front surface (forward surface) of the forward bracket 68 the push-off structure 34.

The lower main bracket 58, the lower reinforcement bracket 60, the first upper bracket 62 and the second upper bracket 64 of the push-off structures 34 are arranged with in the cavity C of the outboard bracket 56 such that they extend close to or approximately perpendicular to the forward bracket 68 and the second portion 72 b of the front bracket 72. In the event of an impact event occurring against the second portion 72 b of the front bracket 72, the lower main bracket 58, the lower reinforcement bracket 60, the first upper bracket 62 and the second upper bracket 64 are oriented to reinforce the forward bracket 68 and the push-off structure 34 such that the impacting force is at least partially transmitted through the push-off structure 34 to the front side member 20.

A description is now provided for the inboard push structure 36 with specific reference to FIGS. 6, 9-15 and 18. As shown in FIGS. 9 and 14, the inboard push structure 36 has an inboard surface 36 a, an upper portion 36 b and a lower portion 36 c. The upper portion 36 b is attached to the inboard surface 46 of the front side member 20 via fasteners F₁, as shown in FIGS. 9, 13-15 and 18. The lower portion 46 c extends downward below the lower surface 44 of the front side member 20. The inboard surface 36 a faces the engine E proximate the lateral side portion 30 a of the engine cradle 30.

The inboard push structure 36 is assembled from an outboard bracket 74, an inboard bracket 76 and a reinforcement bracket 78. The reinforcement bracket 78 is located within a hollow or cavity defined between the outboard bracket 74 and the inboard bracket 76. Further, the reinforcement bracket 78 extends between the outboard bracket 74 and the inboard bracket 76. The inboard surface 36 a of the inboard push structure 36 is defined on a portion of the inboard bracket 76, the inboard surface 36 a facing the engine E.

As shown in FIG. 18, the reinforcement bracket 78 has a gusset or flange 78 a that is welded to an outboard surface 76 a of the inboard bracket 76 and a gusset or flange 78 b that is welded or otherwise fixedly attached to an inboard surface 74 a of the outboard bracket 74.

The outboard bracket 74 of the inboard push structure 36 has an upper flange 80 and a lower flange 82. The inboard bracket 76 of the inboard push structure 36 has an upper flange 84 and a lower flange 86. The lower portion 36 c of the inboard push structure 36 is at least partially defined by the lower flange 82 of the outboard bracket 74 and the lower flange 86 of the inboard bracket 76. The lower portion 36 c of the inboard push structure 36 is angularly offset from the upper flanges 80 and 84 of each of the outboard and inboard brackets 74 and 76.

As shown in FIGS. 9. 13-15 and 18, the upper flange 80 of the outboard bracket 74 and the upper flange 84 of the inboard bracket 76 of the inboard push structure 36 are fixed via fasteners F1 to the inboard surface 46 of the front side member 20.

As shown in FIGS. 9, 14-15 and 17-18, the lower end of the inboard bracket 66 and the lower flange 56 e of the outboard bracket 56 of the (outboard) push-off structure 34 extend downward to a location below the lower surface 44 of the front side member 20.

As shown in FIGS. 14, 15 and 18, the lower flange 82 of the outboard bracket 74 and the lower flange 86 inboard bracket 76 of the inboard push structure 36 also extend downward to a location below the lower surface 44 of the front side member 20. Further, the lower flange 82 of the outboard bracket 74 and the lower flange 86 inboard bracket 76 of the inboard push structure 36 are attached via fasteners to the lower end of the inboard bracket 66 and the lower flange 56 e of the outboard bracket 56 of the push-off structure 34.

Hence, the inboard push structure 36 is fixedly attached to both the front side member 20 and the push-off structure 34.

Further, a majority or main portion of the outboard push-off structure 34 (defined by the outboard section 56 b of the outboard bracket 56) extends outboard from the outboard surface 46 of the front side member 20.

The configurations of the push-off structure 34 and the inboard push structure 36 provide many features to the vehicle 10.

For example, since the outboard push-off structure 34 extends outboard of the front side member 20, in response to an off-center impact event where impacting forces are applied to the front bracket 70 and the outboard push-off structure 34, a portion of impacting forces from the impact event are absorbed in part by the outboard push-off structure 34. Further, another portion of the impacting forces are transmitted from the outboard push-off structure 34 to the front side member 20 and the remainder of the vehicle 10. Thus, the outboard push-off structure 34 can be employed without the inclusion of the inboard push structure 36.

Further, in an embodiment where the inboard push structure 36 and the outboard push-off structure 34, a portion of the impacting forces can possibly deform the front side member 20 causing the inboard push structure 36 to be moved in an inboard direction. Consequently, an inboard surface of the inboard bracket 76 can be moved into contact with the engine E thereby transferring at least a portion of the impacting force to the engine E and the engine cradle 30, thereby disbursing impact forces throughout various areas and structure of the front end assembly 14.

In an embodiment where the inboard push structure 36 is used in the absence of the outboard push-off structure 34, an impact event that deforms the front side member 20 can also cause the inboard push structure 36 to move into contact with the engine E thereby transferring at least a portion of the impacting force to the engine E and the engine cradle 30, thereby disbursing impact forces throughout various areas and structure of the front end assembly 14.

Hence, the outboard push-off structure 34 can be employed with or without the inboard push structure 36. Similarly, the inboard push structure 36 can be employed with or with the outboard push-off structure 34.

The various elements and structure of the vehicle 10 (other than the outboard. push-off structure 34 and the inboard push structure 36) can be conventional components that are well known in the art. Since such elements and structure are well known in the art, these structures will not be discussed or illustrated in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the components can be any type of structure and/or programming that can be used to carry out the present invention.
